I just need an explanation on why I was wrong and why the correct answer is correct
Nookie1986 [14]

Answer:

9

Step-by-step explanation:

<u><em>Definition of: Coefficient</em></u>

A number used to multiply a variable.

<u><em>Example:</em></u> 6z means 6 times z, and "z" is a variable, so 6 is a coefficient.

Variables with no number have a coefficient of 1.

<u><em>Example</em></u>: x is really 1x.

<em><u>coefficients:</u></em>

3<em>x⁴</em>+ 5<em>x²</em> + 1<em>x</em>

<u><em>sum of the coefficients:</em></u>

3 + 5 + 1

8 + 1

Please help! Have had 10 attempts and still haven't got it!

Answer:

28

Step-by-step explanation:

To find the area of the shaded region, you have to start off with the area of the whole triangle. To find that, you multiply the height and length. length=10 height=8 (10x8=80). Then, since it's a triangle, you have to divide it by two (80/2=40). So, 40 is the area of the whole triangle. Then, you find the area of the white region, which is 12 (3x4=12). Finally, you take the area of the white square and subtract it from the area of the whole triangle (80-12=28). You would get 28.
